This is the best money I have ever spent. Gracie is fun. She is reliable, and I can take her places without worry. As you know Gracie is a big girl and she is every strong without TMD training there is now way I would have ever been able to control her. Now she is a pleasure to walk an I have a dog that is trustworthy and reliable. You are great. Without TMD I would not be able to have a dog.
